WEDGE.

Application fled June 20, 1924.- Serial No. 721,182.

To all whom it may comem:

Be it known that I, SAMUEL S. Com, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain newand useful Improvements in Wedges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generall to that class of driving wedges adapte for use more particularly, with alining elements an the holding or securing means em loyed with the various members of a cribbing or forms used in the art'of producing concrete structures.

The present invention has for itsprincipal object to provide a novel and simply constructed, as well as an indestructible driving wedge which can be used over and over a ain, and which is adapted to be used in p ace of the usual and destructible wedge now ordinaril in use and made of wood.

The invention has vfor its further purpose to provide a wedge of a light structure, made of metal, but which is suitabl reenforced, f as to give strength and sta ility to the we e.

Other 0 jects of the present invention not at this time more particularly enumerated will be fully understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention con sists, primarily, in the novel wedge hereinafter more fully described.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a view, showing in sectional re resentation, fragmentary portions of a cribbing wall, a pan of stringer-elements, a members or portion of one of the tyin rods extendin face of the cri ed thereon, and shown in side elevation, an oscillating wedge-engaging holding or tying means and a-wedfe emplo ed in connection therewith, sai wedge ing made according to and embodying the principles of the present invention; and Figure 2 1s a beyond and rom the outer tary portion of one of the outer face of w ich are arranged bing wall, and having mount-- erspective view .of the form of wedge used in connection with the various elements shown in Figure 1.

a Figure 3 is a front elevation of a modified form of wedge; and Figure 4 is a vertical section of the same, said section being taken on line H in said Figure 3.

' Figure 5 is a front elevation of another modified form of wedge; and Figure 6 is a vertical section of the same, said section being taken on line 6-6 in said Figure 5; Figure 7 is an elevation of still another modified form of wedge; and Figure 8 is a vertical section of the same, said section beingrtaken on line 8-8 in said Figure 7. igure 9 is a front elevation, and Figure 10 is a side elevation of a form of wedge, showing another embodiment of the principles of the present invention.

Similar characters of reference are employed in all of the said herein-above de scribed views, to indicate corresponding parts.

Referring now to the several figures of the drawin and especially to Figure 1, the reference-c aracter 1 indicates a fragmenthe cribbing-walls of a mould-form of an suitable size, against usual horizonal stringer-pieces or elements 2. The reference-character 3 indicates one of the usual tie-rods extending across the space of the form, from face to face, as is usual, each tie-rod having a portion 4 which projects through a hole or opening 5 in the cribbing-wall 1, said portion 4 extending between and beyond the stringer-pieces or elements 2, for the arrangement vupon said projecting portion 4 of an oscillatory wedge-- enga ing holding or tying means 6 of any suita le construction.

One form of wedge adapted for use with the various elements heremabove described is illustrated in Figures 1 and 2 of the drawings, the same being made of any suitable metal, and comprising a main bodyplortion 7 provided with an opening, as 8.

xtending upwardly and forwardly from the upper solid portion 9 of the said body 7 is a member 10, which acts as a re-e'nforcement, and also as an anvil for the reception of the blows from the sledge or hammer of the workman when the wedge is to be driven into place.

Of course it will be evident, that with some wedges, this member 10 may be omitthe ted, if desired. The lower portions of the said body 7, adjacent the said opening 8, taper as at 11, and as shown more particularly in Figure 1 of the drawings. As shown, the long opening 8 with which the said body? is provided thus produces a air of elements, in the form of legs 12 an 13, or in other words the body 7 is made yokeshaped, so that it can be readily slip ed over the tie-rod 3, as will be evident. entrally disposed upon these legs 12 and 13, and projecting forwardly therefrom, are tapered ribs, as 14'and 15, which, as will be evident, form the wedging element of the device. An larly shaped re-enforcin ribs 16 may aso be employed, but suc auxiliary ribs 16 may be omitted, as shown in the modified construction illustrated in Figures 3 and 4 of the drawings, but which latter wedge, however, is similar in its construction to the-construction of the wedge represented in said Figures 1 and 2 of the drawings, and herein-above described. If desired, the wedges shgwn in said Figures 1 to 4 inclusive may be provided with nail or screw-receiving holes or perforations, as 17, for securing the wedges in fixed positions, against accidental displacement, after. they have been driven into place.

In the modified construction of wedge illustrated in Figures 5 and 6 of the draw ings, the reference-character 18 indicates the main body of the same, said body being provided with a suitably formed elongated opening 19, so as to provide an upper closed rtion 20 and a lower closed portion 21. ,xtending upwardly and forwardly from this upper closed portion-20 is a member 22,

which acts as a re-enforcement, and also as an anvil for the reception of the blows from the sledge or hammer of the workman when the wedge is driven into place.

The lower closed portion 21 of the said body 18 and the adjacent marginal portions 23 and 24, taper in a manner substantially as shown. As shown in said Figure 5, the elongated opening19 thus-also produces a pair of side-members-25, so that this form of wedge may also be used so as to straddle the tie-rod 3 in a yoke-shaped manner, similar to the construction of the wedges represented in said Figures 1 to 4 inclusive. Centrally disposed upon the said side-members 25, and projecting forwardly from each side-member, are ta red ribs, as 26 and 27 which form the w ging element .of the device, as will be evident. Angularly formed marginal re-enforcing ribs 28 may also be emp oyed, but such'auxiliary ribs 28 may be omitted, if desired.

In the construction of wedge shown in Figures 7 and 8 of the drawings, the reference-character 29 indicates th main body of the wedge, the said body 1n this instance being provided with an elongated opening,

as 30, so' as to provide the said body 29.

with an upper closed portion '31, and a lower open rt-ion 32. Directly connected with the sai closed portion 31, and extending in an upward and a forward direction, is, a member 33, which also acts as a re-enforcement and an anvil for the reception of the blows from a sledge or hammer when the wedge is driven into place. The lower portions of the said body 29, adjacent to the said opening 30, taper as at 34,,and as will be evident from an inspection of said Figure 7 of thedrawings. As with the construction of wedge shown in said Figures 1 to 4 inclusive, the long opening 30 with which the body 29 is provided, thus produces a pair of elements, in the form of legs and 36, whereby the said body 29 is also made yoke-shaped, so that it can be readily sli pedover the tie-rod 3, when put in use.

n this case, the said body 29 and its legs 35 and 36 are respectively provided with forwardly projecting and marginally disposed tapered ribs, as 37, 38, 39 and 40,

which extend entirely from the upper end to the lower end of the device, substantially v as shown.

In lieu of either of the forms of wedges herein-above described, I may produce, a wedge, such as is represented in Figures 9 and 10 of the drawings.

This style of wed e comprises a main body portion 41, preferably formed at its upper'edge with an upwardly and forwardly extending member, 42, which acts as a re-enforcement and as an anvil for, the reception of the blows from the sledge or I hammer of the workman, when th wedge is being driven into place. The lower portion of the said body 41 tapers, as at 43, and centrally disposed uplon said body, and projecting forwardly t erefrom, is a tapered rib 44, which forms the wedging element of the device.

One manner of usin the herein-above described wed es with t e tying block 6, in connection wit the various devices of the mold-form, will be clearly understood from an inspection of Figure 1 of the drawings, and any further description of the same is deemed unnecessary. While I have constructed the herein-above described wedge for use more particularly with the members of a mold-form,-as'i'llustrated in said Fig ure 1, it will be understood that thewedges may otherwise be used, wherever found practicable. Y

I am also aware, that other changes may be made in the neral construction of the wedge, without eparting from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended invention to the exactarrangements and combinations of the various parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings.
